This looks both high utility and well thought-through.

Scraping to JSON is how my unofficial BBC “In Our Time” site works (discussed here https://news.ycombinator.com/item?id=35073603) so I’ve used this approach before.

The post-processing steps are particularly vital (I found that GPT-3 sometimes trips up on escaping quotes in JSON) — and the hallucination check is clever.

This kind of programmatic AI is the big shift iho. I love seeing LLMs get deeper into languages.
